. To all whom t may concern:

Be it known that I, EARL G. YvVnfrnoUs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and` useful improvements in Wastes or OutletValves, of which the following is a specifica# tion.

While this invention may be adapted to more or le'ss general purposes,it is particularly intended as a bathV waste for use in connection withbath tubs. The ordinary wastes such as commonly used have been found tobe more or less objectionable. For instance the ordinary plug IandVchain arrangement is inconvenient Vand unsatisfactory while the standingwaste and overflow which. is usually concealed, not only requiresadditional space for installation but is particularly insanitary Vonaccount'of the `deposit which remains `in the tube. The presentinvention V:relates to a waste or valve construction which will avoidthese objections and which will have various advantages over theordinary devices of this kind.` I

The objects oi this invention are to provide a new and Vimproved wastefor bath tubs or the like; to provide a waste which will'oc'c-upycomparativelylittle room and which will be cleaned `by the Aoutwardpassage of the water in the tub; to Vprovide a waste which may bereadily operated by either the'hand or the foot; to provide a` device ofthisrcharacter which maybe readily takeni'apart for cleaning or repairs;and to provide a waste having such advantages and vnovel features aswill appear more fully from theV following description;

, Gln the accompanying drawings illustrat-j.

ing this invention; l

' Figure 1 is a vertical sectional view of the waste with the valveclosed;

Figure 2 is a similar view showing the j valve in open positioni and jFigure 3 is a detailV of the operating plunger. 1 y

Asillustrated in these drawings, the tub 4 provided with a plug ernipple 5 which engages with an elbowj'or fit-ting 6, lthese parts beinglthreaded at T so that they may be drawn together in the usual manner. A.

washer 8 is inserted between the flange 9 of the fitting Gand the bottomof the tub l in order. to make a tightfclosure. rlhe plug or nipple 5has a cylindrical opening 10 and its lower end 1l is preferably finishedto forni a valve seat.` it also has an inwardly extending annularprojection or rib 12 about midway of its length and another similarprojection 13 adjacent to the bottom. The valve or closure 14 whichrests against the seat 11 isv normally held in raised position by aspring 15 the lower end of which tits in a cup or depression 16 at thebottonfijoi the fitting 6.

` VThe valve 14 has a; valve stem, 17 the `lower end oi which issomewhat reduced and iits in a hole 18 in the valve. This stem isVpreferably removable from the valve but makes a sufficiently tightclosure to pre! .pin 211. The outer edge of the pawl 22 is recessed orcut away to form three points or projections 25, 26 and 27 which are ofproper length to operate in the manner which will presently bedescribed. A toggle arm 2Sy has a substantially spherical head 29 whichtits in the upper end of the stem 17 to form a ball joint for thisarin.The lower end of the arm engages with a recess 30 in the dog or pawl 22and a spring 31 is interposed between the head 29 and cap 19, thearrangement being such that the spring tends to press the toggley arin 28 downwardly and thereby hold the dog 22 in one Y or another positiondepending on the position of the point 30 with Arespect to a linebetween the center of the head 29 and the center of the pivot 24.

As shown in VFigure 1 the valve is closed and the toggle arin 28 tendsto press the proj ection 25 against the inner wall of the cylinder lO.lNhen it is desired to' empty the tub the operator presses down on thecap 19 which moves the valve stem 17 downwardly and opens the valve. issoon as the projection 25 passes over the ridge 12 the operator releasesthe device and the projection being in engagement with the ridge willhold the valve in open position.

When the valve is to be closed the operator presses the cap 19 andconnected parts downwardly until the projection .'26 strikes the ridge13 which causes the dog 22 to turn on the pivot 24 and the arm 28 Vwillbe swung past center thereby tending .next operation.

The discharge from the tub or receptacle 4 passes directly lthrough thevalve or waste and out through a discharge pipe 32 so that itwill tendto lushorjclean the valve.' `The push member and attached parts may bereadily withdrawn from the casing member forcleaning or the like whenthe device is constructed in the-manner shown in these drawings.However, it will ,be readily apparent that the valve and stem may beconnected or a stop provided so that the push member and attached partswill be heldl in position. This wouldpermit the valve to be used in aninverted position if desired. While I have illustrated this device as abath waste, it maybe or' course used wherever applicable and variouschanges may be made in the construction and arrangement Vof parts fin.order to adapt it lfor such other uses. Therefore l do not wish to belimited to thefexact construction herein shown and `described except Vaspointed out in the fol-V lowing claims in whichl claim;

` 1. The combination with a valve member, of a longitudinally movableactuating member and means coacting withsaid actuating member whereby avpredetermined movement thereof vin one directionwill open the valve'vand hold it-in open position and av further movement of the actuating'member in the same direction will `iirst release the valve and thenpermit it to return to closed position.

j2V-VThevcombination withV a valve andvalve4 stein, of meanscoactingwith the stem whereby the valve will beheld open when the stem is moveda' predetermined distance and the valve willV be permitted to close whenthe stem is moved further in the same direction. i i i I 3. Anoutletvalve comprising an outlet member having a valve seat'at the lower endthereof, valve coacting with said'seat, a spring tending to hold thevalve in closed posit-ion, a stem connected with said valve and a'. pawland ratchet device coacting with the stem and arranged to hold the valvein open position when the stem is movedfa predetermined distance andtothen release theivalve and permitV it to .close when the vstem ismoved further in thesame direction.

,The combination .withI a valve, of a.

push member andfmeans .coacting with the valve and push member wherebywhen the push member is moved a given distance the valvewillvbe heldlopen and when the push member again moved further in the sameV pawlmounted on said stem, a toggle arm coacting with. the pawl to Ahold itinadjusted position, said pawl Ihaving aplurality or projections andprojections on the out-V let member adapted to coact withthe pawlwhereby the valve will be heldfinopen position when the `pawl engageswith the firstY projection as' the ,stemV is pressed downs wardly. Y Y YY Y 6. The'combination with avalve stem or the like, of a spring tendingto 'move the, stem in one direction, a; pawl pivotally mounted on saidstem, a yieldingA toggle arm coact-ing with the pawl and adapted to holdit in one or the other of .two positions, said pawl having a pluralityofl projections at differentV 4distances'from'ithe Ycenter and a pairofdetents spaced apart and adapted to coact with said projections, thearrangement being such that when the stem is moveda predetermineddistance the pawl will` engage with the rst detent and will hold thestem inadjusted position and when thefstemis moved a furtherldistance'the other projections will coact with the second detent torelease the pawl andpermit the stem to return Vto its initialposition. fA Y' x 7 Inafdevi'ce ofthe character setforth, the combination'with anoutlet pipe having a valve seat at i'ts lowerend, a Avalve forsuchseat,a springltendingto.,hold the valve against the VVVseat, an upwardlyprojectinfr valve stem, aV combined push i button and guide member atthe upper endv of the stem coacting withsaid pipe, a .pawl VpivotallyVmounted in the stein and-having three projections at the edge thereof,a yielding toggle arm mounted in the .stem and tending to hold the pawlin adjusted position, `two annular ridges in said pipe adapted to'coactwith the pawl, one of said ridges coactingv with one of the pawlprojections for holding the valve open and the 'other ridge coactingwith the other pawl projections'foifswinging the pawl andthrowing thetoggle armpast center, whereby the valve may .again move to closedposition and thepaw-l return to its initial the first named ridge. 1
